HIRAM BARBER, OF CHICAGO, ILLINOIS.

WHIFFLETREE.

SPECIFICATION forming part of Letters Patent No. 562,063, dated June 16,1896.

Application filed September 24:, 1894. Serial No. 523,900. (No model.)

To all whom) it may concern:

Be it known that I, HIRAM BARBER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Eveners or Whiftletrees;and I do hereby declare the following to be a full, clear, and exactdescription of my invention, such as will enable others skilled in theart to make and use the same.

In the accompanying drawings, Figure 1 is a view in perspective of thewooden bar E, provided with the metal jacket J, as used in combinationin the construction of my improved whiffietree WV. Fig. 2 is a view inperspective of the metal jacket J used in combination with the woodenbar E in my imis a view in cross-section, on the dotted line 1 1, of thewooden bar E and of the metal jacket J used in the construction of myimproved whiffietree W.

The object of my invention is to provide a wooden whiffletree or evenerwith a central supporting or strengthening metallic jacket, whereby itsefficiency is increased.

Referring more specifically to the drawings by letter, E represents awooden evener or doubletree of ordinary construction.

J represents myimproved metallic jacket, designed to inclose andstrengthen the middle or central portion of the evener.

WV represents the evener with the inclosing jacket in position.

It will be observed that the jacket is composed of a central oblongtubular portion designed to entirely surround and embrace the centralportion of the evener or whiffletree, and is provided on its upper andlower sides with projecting arms or plates united at their ends by aside loop extending forwardly to a line coincident with the front faceof the central portion and designed to inclose and embrace the frontportion of the evener at a point beyond the central tubular portion, asshown in Fig. 1, thus making the construction of the jacket somewhatskeleton in form in order that the greatest result may be attained withthe least metal, thereby economizing weight and material withoutdecreasing the efficiency of the device.

In the construction of my improved evener or whiffletree for common useI preferably form the wooden evener-bar about four feet in length andfour and one-half inches in width and one and five-eighths inches inthickness and the inclosing jacket about twenty inches in length,including the projecting arms and loops, thus making the latter em braceand operate upon a little less than onehalf of the evener or whiffletreeintermediate of its ends.

I am aware that iron plates have been made use of for many years for thepurpose of strengthening wooden whiflietrees and saving them fromabrasion.

I am also aware that whiffletrees have been provided with a narrowcentral metallic band usually provided with a rearward-extending eye orother device for attaching them to the evener or vehicle, and I do notclaim, broadly, a central metallic band; but I am not aware that anextended metallic skeleton jacket for the purpose of reinforcing andstrengthening a wooden whiffietree or evener has been used, 7 5 and WhatI claim, and desire to secure by Letters Patent, is-

The combination with a wooden whiffletree or evener of the metallicjacket J, formed 80 with a central portion entirely inclosing thecentral part of the evener, and end extensions or arms terminating in alateral or forwardlyextending loop designed to embrace and inclose thefront portion of the evener, substan- 8 5 tially as and for the purposeset forth.

Dated at Chicago, September 20, A. D. 1894.
